I haven't yet found a source for ro/di water. My LFS uses tap water in his tanks. He told me there wasn't any need for ro/di. I figured I was doing pretty good using a 3 stage PUR filter.I have been looking into the ro/di units, mainly just for my own peice of mind. If I can make life for my fish and corals any better, I want to do it.
Here is a picture of my setup a week after the move:
I am still using the 10 gallon sump from the old setup. I have been dreaming about my new sump for a week now. I think I'll use a 30 long I have sitting around.
